Rob,

This is a known bug, first reported by Ethan Alpert.
It appears on IRIX 6 when the build directory in NFS
mounted. It is in our 'support email archive', but has not
yet appeared on the 'known bugs' web page. (Sorry.)

Attached find a patch to src/libsrc/posixio.c.

Alternatively, you can grab the lastest code from
ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.4atd.tar.
This is not fully released because we are still testing it
on 'exotic' platforms like NEC SX4. It works fine on my
6.2 SGI and has the patch already applied, along with other
improvements.
